Whether this website is legit or not is beside the point.
This is because the house has a 50% edge. 16 possibilities (with either a 4x or 8x payout). This is literally the WORST payout of any gambling site I've ever come across. Why would an intelligent gambler like yourself take the worst odds imaginable?
Why anyone would even consider gambling on a site with a 50-75% edge (depending on 4x vs 8x) is the definition of ignorant stupidity. Sorry if I come across abrasive, but most sites have a house edge of 1-5% depending on the game etc.
50% is highway robbery. No doubt about it. Stay away like the plague.
Or conversely, convince me why gambling with such an egregious house edge is a smart decision.
Happy betting (on ANY site other than the aforementioned)
(Here's a free tip -- play online live blackjack and use Hi-Lo to count and you can have an edge OVER the house of 1-2%).
